The system has activated a protection mechanism due to excessively high pressure in the cooling circuit. This can indicate an overcharge of refrigerant or an issue with the outdoor unit.
Click steps to track your progress.
Turn off the air conditioner at the main circuit breaker and wait at least 30 minutes to allow pressures to stabilize.
Ensure the outdoor unit is clean and free of obstructions, allowing for proper airflow and heat dissipation.
If the protection persists, contact a qualified service technician, as issues with refrigerant charge or electrical short circuits require professional attention.
